[rancid] cisco-xr ASR9K and numbered ACL's

Hi Guys

Thanks to you both for the replies. I should have mentioned I’ve tried the
ACL-SORT option being disabled/enabled in config without seeing any
success, I had this line in rancid.conf:

# if ACLSORT is NO, access-lists will NOT be sorted.

I have tried removing “export ACLSORT” with no luck either.

I have 4 or 5 ASR9K’s running 4.3.x and all do the same thing. Perhaps a
better example is this one:

Rancid backs up this:
ipv4 access-list name
 permit ipv4 any 166
 remark the below subnet is currently not in use
 permit ipv4 any 166

What we have configured is:
ipv4 access-list name
 10 permit ipv4 any 166.1xx.xx.xx/28
 20 remark the below subnet is currently not in use
 30 permit ipv4 any 166.1xx.xx.xxx/28

 - so the rancid backup leaves a bit to be desired here I think.

I have:
expect version
This is on centos 6.5, I had the packaged version of rancid installed, an
old 2.3.8 or something but then grabbed 3.1 and compiled it and have
removed the package.

Thanks for all your help with this, I can share more config if you let me
know what exactly.

Cheers, Jos
